Oh nice indeed.

I went to check the docs and they have an even more intricate example with multiple checks https://pkg.go.dev/cmp#example-Or-Sort

	slices.SortFunc(orders, func(a, b Order) int {
		return cmp.Or(
			strings.Compare(a.Customer, b.Customer),
			strings.Compare(a.Product, b.Product),
			cmp.Compare(b.Price, a.Price),
		)
	})
